When the heat dome settled over America and air conditioners roared to life, the federal government quietly reached for wartime-style emergency powers to keep the lights on.
Story Snapshot
- The Department of Energy invoked an old wartime law to compel additional power generation during a June 2025 heat wave.
- President Trump’s earlier national energy emergency and executive order set the stage for rapid grid intervention.
- Coal and oil plants were kept online and pollution limits relaxed to avoid blackouts as demand spiked.
- Environmental groups called it a “false” emergency, while reliability experts warned the grid is stretched thin.
Emergency powers meet a modern heat dome
As temperatures pushed toward triple digits across much of the country in June 2025, the Department of Energy issued an emergency order allowing Duke Energy Carolinas to run certain power plants at maximum output, even if that meant exceeding normal pollution limits.
The point was simple and blunt: avoid rolling blackouts as millions of people cranked up their air conditioning and the Southeast grid strained near its limits.
This action did not come out of nowhere. Section 202(c) of the Federal Power Act, enacted nearly 90 years ago for wartime crises, authorizes the energy secretary to order generators to run during an electric emergency. For decades, that authority sat mostly in the background.
Now, with heat waves getting hotter and demand from data centers and electric vehicles climbing, it has become a live tool in Washington’s reliability toolbox.
How Trump’s national energy emergency changed the rules
On his first day in office in January 2025, President Trump declared a national energy emergency, arguing that years of policy favoring intermittent renewables and plant closures had left the United States with “insufficient” energy production and an “increasingly unreliable grid.”
That declaration framed grid weakness as a threat to the economy and national security, and it cleared the political space for aggressive use of emergency powers to keep aging fossil plants online.
Three months later, an executive order on “Strengthening the Reliability and Security of the United States Electric Grid” told the Department of Energy to use Section 202(c) whenever needed to keep “critical” plants running.
It also ordered a national “Speed to Power” effort and a detailed report on grid reliability, including a uniform way to measure reserve margins and flag regions “at risk” of shortfalls. In plain English, the White House gave the energy secretary both the marching orders and the data framework to justify rapid intervention.
From one-off response to a pattern of grid intervention
By summer 2025, emergency orders were no longer rare. After the June Duke order during the heat wave, the Department of Energy followed with several more under Section 202(c), extending the life of coal and oil units that were supposed to retire.
A Department of Energy press release that July announced a fifth such order to protect the Mid-Atlantic grid, again citing the need to maintain reliability under stress conditions. What had been sold as last-resort authority was starting to look like a standing policy lever.
The July 7 “Evaluating the Reliability and Security of the United States Electric Grid” report then wrapped these moves in technical language.
It introduced a national method to judge resource adequacy and identify “at-risk” regions, spotlighting large systems like PJM in the Mid-Atlantic and Midwest as facing serious reliability challenges if retirements continue.
While the report did not change the law, it gave the Department of Energy a data-backed narrative: if the math indicates a region is at risk, keeping specific fossil units running under 202(c) can be framed as serving the public interest.
Critics say “false emergency,” supporters say “common sense”
Environmental advocates saw something very different. Earthjustice blasted the Department of Energy’s series of orders as a way to “extend the lives of polluting power plants under [a] false energy emergency.”
Their argument rests on two points: the lack of released real-time grid data showing that reserves truly fell to emergency levels, and the financial benefit to coal and oil plant owners when the government orders them to run longer than markets demand.
From this view, the question is not whether emissions rose for a few scorching days, but whether families and hospitals kept the power on during dangerous heat.
Studies show that when the grid fails during a heat wave, the share of people at risk of heat illness explodes. Faced with that, using every legal tool to avoid blackouts looks less like “overreach” and more like basic duty, as long as it stays temporary and transparent.
The deeper problem: a grid built for yesterday’s weather
Beneath the legal battles sits a larger reality both sides quietly admit. The North American grid was planned and built for a milder climate and a different mix of power plants.
Demand now rises not just for air conditioning but also for data centers, electric vehicles, and electrified industry, while steady coal and gas units retire faster than firm replacements come online. Federal regulators and independent experts warn that reliability is “deteriorating” as this squeeze grows.
Emergency orders can paper over that gap for a day or a season, but they cannot rebuild transmission lines, add firm capacity, or modernize planning. That will take years, clear rules, and honest tradeoffs between cost, reliability, and emissions.
Until then, when the next brutal heat wave hits, you should expect the same basic story: grid operators warn of thin margins, utilities ask Washington for help, and the Department of Energy dusts off its wartime-era powers to keep power flowing, even if it means more smoke from old stacks for a few more nights.
